Abstract: Abstract:         The disclosure shows a telephone range extender which is automatically adaptable to the length of the connected subscriber loop.  A loop resistance detector within the range extender discriminates between loops within a plurality of ranges of lengths.  For extremely short loops not requiring range extension, the range extender circuits are disconnected from the loop.  For intermediate length loops, the gain of a bidirectional voice frequency amplifier is set at a low value to provide just sufficient gain for these loops.  For longer loops, the gain of the amplifier is increased to provide sufficient amplification for the longer range.  For extremely long loops, the range extender is disconnected since such loops must be served by remote amplification facilities.  An automatic range extender of this type is shown connected behind the first stage of the central office switch in order to concentrate range extenders on a larger plurality of subscriber loops.

Abstract: ABSTRACT      For an automatic cannon, a pneumatic bolt and sear buffer comprises a housing fixed rearwardly of a breech ring, a cylinder, an end plate and a low mass piston projecting forwardly through the cylinder.  A pin trans-versely installed through the piston, into slots in the cylinder and housing, limits relative axial movement between the piston, cylinder and housing.  A forward cylinder flange also limits rearward cylinder movement relative to the housing.  Pressurization of gas in a pressure chamber defined by the cylinder, piston and end plate is through an end plate valve.  A bolt sear is pivotally mounted to a sear bracket extension of the cylinder, forwardly of the piston.  After firing, recoil impact of a reciprocating bolt assembly drives the piston rearwardly into the cylinder, and upon bolt searing the cylinder is pulled forwardly relative to the piston; in both cases the buffer gas is further compressed, acting as a massless spring.  A sear support or keeper is pro-vided to prevent hitting and bouncing of the sear by the bolt assembly on searing up.

Abstract: P 97 4748 LOG HANDLING AND TRANSPORT SYSTEM ABSTRACT OF THE DISCLOSURE A grouping of elongated objects such as logs are supported in a pair of elongated wire slings that are releasably attached to an overhead frame. When loading logs onto ships, the overhead frame is attached to the ship's gear for use. For loading, the frame is lowered and a load of logs is surrounded at spaced apart locations with the wire slings. At each end of a wire sling is an eye which is secured within a releasable hook mounted in pairs on the frame. A sliding snap hook fixed to one eye of each sling is hooked to the opposite eye so as to form a continuous sling about the logs. The load is then lifted into the ship and placed after which the releasable hooks release the continuous wire slings allowing theload of logs to conform to the volume where it is placed. The slings remain in place about the logs during the voyage.

Abstract: ABSTRACT OF THE DISCLOSURE:         The present invention relates to a hydraulic-motor-driven two-unit cross-country vehicle, such as a forest tractor, consisting of tractive unit suspended on a bogie and provided with a dual hydraulic pump and with a drive engine for same, and of a load-carrying unit suspended on a bogie and coupled to the tractive unit.  The pairs of wheels of both bogie components, both of the tractive unit and of the load unit, being driven each by a hydraulic motor of its own.  Prior art vehicles of this type are provided either with a steering mechanism operating by means of steering clutches and brakes or with a steering mechanism operating by means of the articulated joint.  A drawback of these steering systems is that they involve a certain slowness, which limits the manoeuvrability of the vehicle especially in difficult terrain, or that a great deal of the power output is missed during a steering manoeuvering because of the clutches and brakes.  According to the present invention both of the driving hydraulic motors of the tractive unit are cross-connected with both of the driving hydraulic motors of the load unit so that the hydraulic motors cross-connected with each other are, during each steering operation, made to rotate their respective cross-connected pairs of wheels at the same speed of rotation as compared with each other, which results in that the vehicle has almost maximal power output on every wheel.

Abstract: MICROCONTROLLER FOR DISK FILES                  Abstract A microcontroller for controlling the bidirectional transfer of data between a control unit and a plurality of disk drives is disclosed.  The microcontroller has a fixed machine cycle time for executing each instruction and is arranged to fetch the next instruction during the execution of the current instruction.       The microinstructions are stored in an addressable memory and each addressed instruction is transferred to a control subsystem in response to the operation of a second subsystem whose function is to generate the address of the next instruction to be executed. A third subsystem is provided for executing the instructions which is also employed during branch type of instructions for assisting the second subsystem in generating the next address.   The second subsystem also functions to supply the third subsystem during execution of certain instructions, data to be stored for use during subsequent instructions.       The subsystem for executing instructions is characterized by a plurality of data sources which are selectively interconnected through the ALU to the ALU register during the input phase of a machine cycle and a plurality of data destinations which are selectively connected to the output of the ALU register during the output phase of a machine cycle.  One of these destinations is the subsystem for fetching the next instruction.       The subsystem for fetching the next instruction is characterized by a plurality of partial address generators which operate selectively with the other subsystem to generate the complete address of the next instruction.       The controller also employs a mu1tilevel priority trap system for interrupting the normal sequencing of instructions in response to events occurring in the devices being controlled or events within the microprocessor.

Abstract: Div. I     GRADIENT INDEX OPTICAL WAVEGUIDE     ABSTRACT OF THE INVENTION         In the method of making a preform for a high numerical aperture gradient index optical waveguide, the concentration of two dopant constituents is changed during fabrication.  Concentration of the first dopant, GeO2 is changed radially as the preform is built  up in order to produce the desired radial refractive index gradient.  The concentration of the second dopant, B2O3 is changed radially to compensate for the radial change in thermal expansion coefficient caused by the varying GeO2 concentration.  B2O3 is added to the cladding layer to make the thermal expansion coefficient of the cladding equal to or greater than the composite thermal expansion coefficient of the core.  The magnitude of residual tension at the inner surface caused by thermal expansion gradients is reduced and premature cracking of the preform is eliminated.

Abstract: ABSTRACT            EXPRESSION OF POLYPEPTIDES IN YEAST      In order to make a yeast strain capable of expressing a desired polypeptide (e.g. leukocyte interferon D) which it does not normally make or use, it is transformed with an expression vector.  This is obtained by producing a transfer vector which has respective origins of replication and phenotypic selection genes derived from both bacteria and yeast, and inserting into it DNA fragments:  (i) coding fox the desired polypeptide;  and (ii) comprising a yeast-derived promoter.  The insertion is effected so that 'start' and 'stop' signals are provided, and these and the promoter can control expression of the polypeptide, and so that the replication origins and phenotypic selection genes of the transfer vector are still functional.  Thus the expression vector and its precursors can replicate, and their presence can be recognised, both in yeast and bacteria.  Bacteria are used for amplification.   The yeast-derived phenotypic selection gene may complement a mutation carried by the strain to be transformed.
